Does Peter walking on water show our innate human potential to do miraculous things?

 First He did not do this at his own discretion, Jesus had to bid him to come. Peter did not all of sudden decide that he can walk on water. Neither was this tried or repeated at any other time by him or any other disciple.

Matt 14:26-33: “And when the disciples saw Him (Jesus) walking on the sea, they were troubled, saying, "It is a ghost!" And they cried out for fear. But immediately Jesus spoke to them, saying, "Be of good cheer! It is I; do not be afraid." And Peter answered Him and said, "Lord, if it is You, command me to come to You on the water." So He said, "Come." And when Peter had come down out of the boat, he walked on the water to go to Jesus. But when he saw that the wind was boisterous, he was afraid; and beginning to sink he cried out, saying, "Lord, save me!" And immediately Jesus stretched out His hand and caught him, and said to him, "O you of little faith, why did you doubt?" And when they got into the boat, the wind ceased. Then those who were in the boat came and worshiped Him, saying, "Truly You are the Son of God.”

The new age view is that Jesus is the way-shower, that he is demonstrating what we all can do because we have the power within. If one actually reads through the account it becomes clear what took place.

Notice Peter says “command me to come to You on the water” He needed Jesus, he did not initiate it himself.  Jesus called him and Peter being impetuous was willing to try it. As he saw himself walking he looked at the rough waves and lost faith in Jesus command and began to go down crying out for Jesus to save him. when he took his eyes off of Jesus he began to sink. Jesus tells us the answer, that had doubted and lost faith, the Greek word oligopistos  means to lack confidence in the word spoken to him. He doubted- distazo- properly, to waver doubt.

When Jesus comes on board the wind ceased showing He was in control of the event and nature. Their focus was toward Jesus – worshipping him, calling him the Son of God. It was not his power but Jesus that kept him afloat with the qualification of him trusting him.
